Surface treatment process of sheet metal chassis

Surface treatment process of sheet metal chassis

Powder spraying: the powder is polarized and uniformly attached to the product surface with opposite polarity under the action of electric field force. It belongs to physical change. Principle of powder spraying process: electrostatic powder spraying: it mainly polarizes the coating (powder) through the electrode, and then brings the opposite charge to the object to be sprayed. Under the action of electric field force, the powder is evenly attached to the surface of the object. Features of powder spraying process: electrostatic powder spraying will not cause atmospheric pollution, and the powder can be recycled to reduce the consumption cost of materials. The film has superior performance, acid resistance, alkali resistance, salt resistance, good corrosion resistance, and high adhesion.
